Good news - Quantum memory 'world record' smashed

[Spudders]

I'm sure you'll all agree this is excellent news.

I won't copy & paste the whole article, but here are a few of the key points for discussion.....

 

A fragile quantum memory state has been held stable at room temperature for a "world record" 39 minutes

 

"Qubits" of information encoded in a silicon system persisted for almost 100 times longer than ever before

 

The trouble with qubits is their instability - typical devices "forget" their memories in less than a second.

 

Magnetic field pulses were used to tilt the spin of the nuclei and create superposition states - the qubits of memory.

 

"We've managed to identify a system that seems to have basically no noise."

 

Their memory device was built with a highly purified form of silicon - free from the magnetic isotopes which interfere with the spin of nuclei.

 

A number of intriguing challenges still remain. For instance - will it be possible to precisely control the local electron-nuclear interaction to enable initialisation, storage, and readout of the nuclear spin states?

Thank F... for that. the fact that they could seem to break the minute mark was beginning to play on my mind. I can sleep easier now.

Quite frankly long overdue, boffins at Porton Down were near the one minute mark in 1940.
